About GasGuard Chicago
A gas contractor built around one city’s housing stock, one utility’s procedures, and one stubborn idea: the paperwork, the pricing, and the gauge should all tell you the same story.
Built for the Buildings This City Actually Has
Chicago’s gas problems aren’t generic, so a generic gas company was never going to serve them well. This city runs on balloon-frame bungalows and worker cottages from the 1910s–40s, two- and three-flats past their hundredth birthday, black iron threaded by men who retired before color TV, and meters placed wherever 1925 found convenient. Piping like that doesn’t need a franchise with a national playbook — it needs people who work on this stock, under this building code, with this utility, every single day.
That’s the whole founding idea. We stay inside the city limits on purpose: one permitting office whose process we know cold, one set of placement and testing rules, one utility — Peoples Gas — whose restoration desk, meter procedures, and paperwork expectations we deal with constantly. Specialization isn’t a marketing line here; it’s the operating model.
How We Work — the Non-Negotiables
- ✓Paper first. The permit is filed before pipe is cut — every job, no exceptions — because unpermitted gas work surfaces at exactly two moments: your insurance claim and your closing.
- ✓The gauge decides. Every repair, install, and relocation ends with a pressure test you’re welcome to watch — air or nitrogen, never live gas — and a signed affidavit with readings and photos.
- ✓Findings before invoices. You see what we found, what it means, and what it costs — in that order — before any decision is asked of you. A failed reading is information, never a sales lever.
- ✓Published pricing. Our service pages carry real ranges — visit fees, repair tiers, per-foot install rates, the ~$75 permit — because “call for quote” usually means “depends how you sound.”
- ✓Honest boundaries. The meter and service line belong to Peoples Gas; the piping belongs to you and legally needs a licensed contractor. We tell you which side of that line your problem sits on — even when the answer is “that one’s free, call the utility.”
- ✓Built to be serviced. Drip legs at every appliance, unions and shutoffs placed for the next tech, every line traced and labeled — the small decisions that show up in year fifteen, not on the invoice.
Six Services, One Standard
Everything we do lives on one of these pages — each with its process, its pricing, and its answers published in full.
Gas Leak Repair
Same-day response for the smell, the hiss, and the red tag — pinpointed, fixed, tested, documented.
Gas Leak Detection
Instrument-grade answers when something’s off but nothing’s found — including the leaks soap and noses miss.
Gas Line Repair
Century-old black iron, corroded fittings, failed joints — repaired or honestly recommended for replacement.
Gas Line Installation
New lines sized from load math, permitted before pipe, tested before flame — ranges, grills, tankless, generators.
Pressure Testing
The held gauge and signed affidavit behind restorations, closings, permits — and peace of mind.
Meter Relocation
Both halves of the move — utility coordinated, piping rebuilt, every line labeled and tested.
About Our Reviews
Our review section goes live with the business, and it will only ever hold reviews from real customers at real Chicago addresses. We don’t write them, buy them, trade discounts for them, or launder them through third-party services — in a trade where you’re trusting someone with the pipe behind your walls, a fabricated five-star is a lie about the thing that matters most. If you’ve worked with us — or even just used this website — the feedback page explains exactly how to be heard, and yes, the owner reads every message.
See If We’re the Right Fit.
Read any service page, run our own vetting questions on us, then call. We’ll earn the job on the phone or tell you honestly who should have it instead.

Published pricing. Every number we charge is on this website before you ever call — detection $75–$400, pressure tests $75–$150 with a signed affidavit, minor repairs $120–$300, and the full table on every service page. Permits, always. A City of Chicago permit (~$75) is filed before pipe is cut on every job, because unpermitted gas work surfaces at exactly the wrong moments — sales, claims, disputes. Proof, not promises. Every repair ends with air or nitrogen held on a gauge and a dated affidavit you keep.
Where we work: all of Chicago, 24/7 — with dedicated neighborhood pages for Lakeview, Lincoln Park, Portage Park, Bridgeport, McKinley Park, Beverly, and Morgan Park. Practical guides for owners, renters, and landlords live in the help center.
